CUSHION STRUCTURE. '3,285,063. Sredtion of Letters Patent. Patented Nov.I9, igi.

Application filed March 1, 1916. Serial No. 81,485.

To all whom z't may concern.'

Be it known that I, FRANK P. DARGY, ya citizen of the United States,residing at Kalamazoo, county of Kalamazoo, State of Michigan, haveinvented certain new and useful Improvements in Cushion Structures, ofwhich the following is a specification.

This invention relates to improvements in cushion structures.

The main objects of this invention are:

First, to provide in a spring cushion structure an improved means forsecuring the upholstery cover to the spring supporting frame.

Second, to provide an improved spring cushion structure in which thesprings may be mounted completely upon their supporting frame and theupholstery securing frame formed independently and quickly assembledupon the spring structure.

Further objects, structural details, will definitely appear from thedetailed description to follow. v

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure I is a detail perspective view of my improved spring cushionstructure, a portion only of the springs being shownv and theupholstering being omitted.

Fig. II is an enlarged detail vertical section through a completedstructure embodying the features of my invention.

Fig. III is a perspective view of the 11pholstery frame. l

Fig. IV is an enlarged detail vertical section on a line correspondingto line 4 4 of j Fig. III, showing structuraldetails. f

Fig. V is a detail section on a line'correspending to line 5-5 of Fig.III, showing further structural details.

Fig. VI is a detail plan view cfa slightlv modified construction of theupholsteryr frame.

Fig. VII is a detail vertical section corresponding to that of Fig. IVof another mod 1- ied form of my invention, the modificationl andobjectsv relating to in the direction of the little are provided withtop and bottom supports. Y

These supports, in the structure illustrated, are substantial duplicatesso that a description of one will suitice. The spring support comprisesthe border frame 2 formed of wire and the supporting wires 3 arranged incrossed sets, the ends of the wires being secured at 4 by wrapping thewires around the border frame. The support wires 3 are arranged in pairsand provided with offsets 5 which engage the top and Ibottom coils ofthe springs, the oii'sets being of such length that their ends, whichform shoulders 6, engage the oute'r sides of the coils. The oiisets areprovided with reversely projecting loops 7, that is, the loops projectin the direction opposite from that of the offsets. These loops arearranged centrally of the offsets and disposed on the inside of thecoils. The support wires are locked -to the coils by means of thelocking wires 8, which are threaded through the loops on the side of thecoils opposite the oilsets so that the coils are 85" locked within theoffsets and being engaged in cross section to receive 'fthe tackingstrip 10. The upholstery'frame 9 is provided with anges 11 and 12 at itsedges whichhre clamped upon the tacking strip. The lower Bange 12 is inthe form 'cfa bead to provide a finish and to protect the edges of the,covering 13. The upholstery comprises an inner cover 14, the filler 15of hair or suitable material, and the outer cover 13. The

upholstering maybe tufted or. otherwise, as

desired. Y The edges ofthe covering are secured vto the` upholstering.frame 9v by means of the tech-s i6. fi iuishing;n strip or gimp" a i? ispreiereciy provided. rEhe techs ere driven into the teciring strip endere preierehiy ci such length thet they engage the hach ci the chenneiend ere turned or cienched. rThe uphoistery ironie is siipped over thespring border treme 2 and secured theretooy ineens ci the tongues 18which ere struck out oi the uphoistery ironie end ciernped over thecushion reine 2, es shown in Fig. i'i. riChis enables the convenient ondquich esseinhiing of the parts.

' "itl is 'ound that even when the techin strips ere izornied oi veryhigh grade Wo-oc especieiiy iadopted Vior the purpose considerableproportion ci there spiit et the corners wheny hent to iorrn orafterward when they dry out. To prevent this sind to etectiveiy supportthe teching strips et'the corners i provide the pericreted corner stripsi9 Whichereerrenged over the techying strips and engaged end retained hythe iienges oi the uphoistering freine, being damped oy the euges sothat they seeureiy heid in piece ege-inst the teching strips. i heperiorstions permit the driving or" techs or securing the coveringaround the corners ofi the trarne. rfriese corner strips also serve toprotect the techno strips from the edges ci the bottoni iienge i2 whichtends to split there when the rerne is bent up, it being the practice tosecure the teching strip in the channel end then bend or iorm the seine.

The end 2G ci the teciring strip is errenged to iep the joint 2i oitlthe upholstery freine 9 (see ig. iii), end serves es :i suitehieconnection between these perte.

in the niodiied structure shown in Fig., Vi the upholstery ireine isformed in sections 22 end 23 connected icy the coupiing,n sieeves 2t,there being seine spring1 constructions in Which the upholstery rre-reeshown in iig. ii connothe ocnvenientiy positioned editer the uphoisteryhas been ettrfched thereto.
